Call in the Specialist! When your horse enters Stage E he's asking for some time with the pros. These are correction bits and should be used by experienced riders only. Here tiny twists, very high ports, and highly complex mouthpieces are key components. Excellent bit for a well trained horse. Copper creates a wet, soft mouth for more feel and will bend to conform to mouth. Mullen relief mouthpiece creates even pressure across the bars and tongue to eliminate nutcracker effect. Ride with light hands-DO NOT TIE HORSE IN THIS BIT.
